Shit, shit, shit. Android display all black after turning on inverted colours. Doesn't reset to normal on reboot and now I can't unlock the phone. Any tricks to be done in recovery?
@sophie might help to tell us the actual phone model!
anyways, this looks roughly like a 2023 motorola, so chances are it outputs displayport over USB-C and you could try attaching an external screen to see if there's anything shown that just gets lost in color inversion
